See F14 kernel.spec, starting around line 100. There are no with/without
pae or pae_debug bits there, so you're passing in options that are, atm,
completely meaningless. The assorted pae bits you see in the spec are
internal-only variables. Note that --without smp doesn't do anything on
any arch but 32-bit ppc either. Really, what you want, is --with baseonly,
though it looks like the baseonly target is missing the bits to also
disable the pae build. I swear we added pae bits in at some point, but
they sure don't seem to be there right now...
